The Align Tactical Thumb Rest Takedown Lever integrates an ergonomic ledge for the support hand’s thumb to firmly lockdown. The rest serves as a brake against muzzle flip, providing faster follow-up sight pictures. Increased surface contact with the pistol reduces support hand slippage. The thumb rest is an excellent index point for a consistent high thumbs-forward grip.

Owners can swap the takedown lever in seconds to offer maximum control and speed in SIG Sauer P320 pistols for a competitive edge.

P320 Takedown Lever Product Specifications

The thumb rest extends 30 degrees forward of the center of rotation. The thumb will direct applied pressure (counterclockwise) towards the over-travel stop to remain locked in place rigidly. Features improved leverage for easy disassembly.

Establishing a two-handed grip creates a naturally angled cant of your support hand thumb. Incorporating a secondary receiving slope of 15 degrees allows for evenly distributed thumb pressure. In addition, it serves as a guide for settling into the proper contact position (with the center of the thumb’s pad fingerprint flatly pressed to the rest).

This takedown lever protrudes 0.4 inches (10mm) from the grip module for a comfortably slim footprint that creates approximately half a thumb width of resistance area. Horizontal serrations offer excellent traction against recoiling muzzle rise without being abrasive. Perfectly sized with aesthetics to match.

Fit Guide

  • Will fit most factory standard and Grayguns Laser-Sculpted SIG Sauer P320 grip modules, including Standard and X-Series modules.
  • Fits the M17 and M18 versions

Ensure the pistol with this takedown lever installed will fit in your holster!

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
